London Underground's iconic Tube map has been updated a tweaked many times since Henry Beck's original design in 1933.

But London Underground map expert Max Roberts has dispensed with Beck's classic design and produced a radically different-looking map using a combination of straight lines, curves and circles.

Mr Roberts was inspired to update the map following the introduction of the orbital London Overground.

"If we really are going to throw away the design rules, and switch emphasis to orbital lines, then we need at least one full circle to make the concept convincing. However, forcing the Circle Line into this shape is a bad starting point. Its actual route is nothing like circular," he told the Going Underground blog.

"The Overground loop is far more suited to this sort of design abuse, and a much more interesting shape is possible for the Circle Line itself.

"Although parts of the map suffer horribly (Thameslink to West Hampstead for example), it is surprising just how much of London is resilient enough to withstand the attack. Intriguingly, this is the only map I have ever seen where Crossrail looks convincing, especially in East London."

However, Mr Roberts does not think the map is ready to send to TFL. "No great advances in usability here, but it was fun to make it."
